6 Claims.

The invention pertains to containers especially adapted for use asbutter tubs, and has for its general aim the provision of a butter tubof improved construction which permits of economical manufacture, whichfacilitates shipment of the tubs, and which is capable of preserving thecontents thereof in a sanitary condition.

With this aim in View, one object of the invention is to provide a novelconstruction for butter tubs permitting the use of light weightmaterials without sacrificing strength and rigidity, and permitting thenesting of both the body and cover sections for the sake of compactnessin shipping. l

Another object is to provide an improved construction for the upper endportion of the tub adapted to insure a tight fit of the cover on thebody.

The objects of the invention thus set forth, together with other andancillary advantages, are attained by the construction and arrangementillustrated in the accompanying drawing forming a part hereof, in which:

Figure 1 is a side elevational view of a tub embodying my invention. Y

Fig. 2 is a fragmentary Vertical sectional View through one side of thetub.

Fig. 3 is a fragmentary transverse sectional view taken in the plane ofline 3 3 of Fig. 2.

Fig. 4 isla side edge view of a fastening device for the cover.

The improved tub comprises a main or body section having an annular sidewall 'I and a bottom wall 8 with metallic reinforcing hoops 9 and l0 atthe lower and upper ends of the side wall; and a cover sectioncomprising a top plate 11 having at its outer peripheral edge an annularring 12 with a tapering flange 13 adapted to telescope the upper hoop10.

The side wall 7 of the body section is preferably made of a lightfibrous material such as that commonly known as ply-wood. It is madefrom two or more sheets rolled into annular form with the overlappingends suitably secured together. To permit of the nesting of a pluralityof body sections together during shipment, the side wall ofthe tub isflared or tapered outwardly and upwardly from its lower end.

In securing the bottom wall 8 in position, advantage is taken of thetapering character of the ide wall 7 to insure a tight seal for thebottom of the tub. To attain this result, the bottom wall is made ofsubstantial thickness so as to insure the necessary rigidity, and itsperipheral edge, which is of a diameter slightly greater .than that1932, Serial No. 630,810

of the side wall at the final point of engagement therewith, is taperedas indicated at 15 so as to conform substantially to the taper oi theside wall. Moreover the hoop 9 is first applied to the lower end of theside wall in snugly fitting relation thereto, so as-to provide in effectan annular outer abutment in opposed relation to the peripheral edge ofthe bottom wall. Thus it will be apparent that when the bottom wall ispressed into position with the application of considerable force, as forinstance by hydraulic pressure, a wedging action occurs between the sidewall and the edge of the bottom wall causing the lower end of the sidewall to be clamped tightly between the hoop 9 and the bottom wall.

To form a stop or abutment definitely limiting the downward movement ofthe bottom wall, the hoop 9 is made from a metallic strip of substantialwidth and its lower edge portion is turned inwardly and upwardly as at16 to form an annular shoulder 17. Such inturned portion of the hoopalso serves to increase the effectiveness thereof as an abutment in theclamping action above referred to.

The upper hoop 10 is also made from a fiat metallic strip of substantialwidth, and is especially shaped to provide a lower annular fasteningband 18 fitting snugly about the upper end of the side wall in spacedrelation to the upper end thereof; a top flange 19 overlying the upperend of the side wall so as to form a smooth seat for the cover plate 11;and an intermediate seating rim 20 flaring or tapering outwardly anddownwardly and bearing at its upper edge against the upper outer edge ofthe side wall. The lower edge of the seating rim 20 being spacedoutwardly from the side wall is connected to the fasening band 18 by anannular portion 21 which constitutes in effect an annular strutsupporting the lower edge of the seating rim against inwardly directedpresn sure. The hoop is secured in position on the side wall by piercingindentations 22 therein at spaced points, thus eliminating the use ofnails.

The cover plate 11 is also preferably made of ply-wood, and is made of adiameter such that its outer lower edge portion is adapted to rest uponthe top seating ange 19 of the upper hoop 10. .An annular groove 23formed in the outer peripheral edge of the cover plate is adapted toreceive loosely the ring 12 carrying the cover flange 13.

The ring 12 and cover flange 13 are formed from a flat strip of metal,with the ange bent downwardly from the outer edge of the ring at anangle such as to produce an outwardly and downwardly tapering surfacesubstantially conforming to the outward and downward taper of theseating riin 20. By this construction a wedging action is producedbetween the cover ange 13 and the seating rim 20 which insures a tightsealing fit between the cover and the body of the container, it beingobserved in this connection that the sealing is iirrnly supported by theannular strut 2i and by engagement at its upper edge with the upperouter edge of the side wall. At the saine tiine the inward pressure onthe seating rim is transmitted through the annular strut 2l to force thefastening band i8 tightly about the side wall of the container. Afeature of primary importance is the outward flaring character of thecover flange which permits a plurality of covers to be nested togetherin compact relation for shipment.

If desired, the cover inay be fastened in position on the body by rneansof a plurality of fastening devices in the form of metallic strips 24,the lower ends of which are inserted between the fastening band 18 ofthe top hoop lo and the side wall 7 before the cover is applied. Withthe strips thus engaged with the hoop l0, they are bent upwardly andover the upper outer edge of the cover plate and fastened thereto as bymeans of tacks 25. The latter are preferably inserted through inwardlyfolded portions 26 with the heads of the tacks concealed and retainedwithin the folds.
